It might be a good idea. Another potential advantage is that then
we'll have two separate entries on test.winehq.org.
I'm okay either way though.

This reminds me that's probably better to do something similar WRT the
window for d3d9 too, in the previous patch.

Same point WRT texture readback as the previous patch.

More of an open question than anything: is the "global" constant
buffer always supposed to be at index 0?
